Walnut crops ripen in autumn and the trees grow well in the South Australian climate with its warm summers and cool winters. Harvesting is undertaken by shaking the walnuts from the trees with the nut protected by an outside shell with the kernel inside being the edible part.
If you are purchasing walnuts in the shell, select clean nuts free from cracks and holes, and which feel heavy for their size. When buying hulled nuts select crisp, plump kernels with a light skin colour, avoiding any that look rubbery or shriveled. To keep nuts in the best condition, store them in an airtight container in the fridge. Unshelled walnuts should stay fresh for up to six months if stored in the cool dark place.
Walnuts are a great addition for many meals – the Nuts for Life website has a great range of recipes for walnuts and other nuts grown in Australia http://nutsforlife.com.au/. Nuts for Life is an initiative of the Australian tree nut industry to provide information about the nutrition and health benefits of tree nuts.
You can find walnuts at Adelaide Showground Farmers’ Market at the McLaren Vale Orchards, B&A Andonopoulos, Rich Pickings and The Food Forest stalls at Adelaide Showground Farmers’ Market.
